As another person currently residing in Baltimore (and who just re-signed a lease to stay in a city I've enjoyed living in), it's worth pointing out that when people talk about "systemic" issues in policing and law enforcement, they're talking about things like the fact that for the last, oh, literally 162 years, Baltimore PD has not been administrated within the City of Baltimore, but instead by state lawmakers in the capital, Annapolis, which is around a 45-minute drive away. It's only been during the most recent local election that control was moving locally instead[1][2][3].
This kind of thing has resounding consequences. Baltimore is a city with a complicated history; for one thing, it's down from it's peak of almost 1M people to under 600k [4]. There's a significant history of racism in Maryland at large. There's a lot of fundamental issues, ranging from food deserts to lack of public transportation among the poorer areas. But to say that "[I]t would take Ra's al Ghul to resolve the problems of this city" is not true. It's certainly not all sunshine and roses, there's a lot of work being done at the grassroots as well, from new local investigative news organizations like the Baltimore Banner being funded to small makerspaces being set up in the now-plentiful well-built, but unused buildings that cities like Boston or Washington, DC. would only dream about having near their harbor or highways, and it's unfair to dismiss these things as being worthless.
